After installing a more powerful and oscilanting fan, I'm noticing some leaves hanging somewhat downward and in a slight claw-like shape. Could this be related to the wind?
Hello my friend, do NOT point the fan straight on the plants. You want to blow the wind in between plant and lamp. When the leaves are gently fibrating is enough. Now they are looking so sad because they evaporate the moist inside the leaves too fast!
More likely than not unless other factors have changed. Wind burn can happen to plants just like people, you don't need a gale in your tent. =)
Try deflecting to force a little by bouncing your airflow off either a wall or the floor of your tent. You're just trying to move air around.
